""In "Classic Hubs" mode, you will begin each episode in a central hub map, with access to 4 other maps. You will find keys to open locked doors along your way. After approaching a lock, your Quest Journal will provide hints on where to look for the key. Once you have the keys for the blue portal, you can exit the hub.

"Easy Hubs" mode is similar to Classic Hubs mode, but keys will only be required to unlock the blue portal and exit the hub. Each map in the hub will hold one key.

In either mode, completing a hub will be followed by two maps in linear sequence, including a boss battle.

The expansion contains no hubs, and all maps are in linear progression only. Find the key to exit each map!""

Could someone explain whether the "Easy Hubs" mode contain levels that are NOT in the "Classic Hubs" mode?
I have finished the game on "Classic Hubs" mode and wonder if there are any levels I haven't played through in the game's other mode.
